Chlorinated organic pollutants constitute a significant category of persistent due to their widespread presence in the environment, which is primarily attributed expansion agricultural and industrial activities. These are characterized by persistence, potent toxicity, capability for long-range dispersion, emphasizing importance eradication mitigate environmental pollution. While conventional methods removing chlorinated encompass advanced oxidation, catalytic bioremediation, utilization biochar has emerged as prominent green efficacious method recent years. Here we review biochar's role remediating typical organics, including polychlorinated biphenyls (PCBs), triclosan (TCS), trichloroethene (TCE), tetrachloroethylene (PCE), organochlorine pesticides (OCPs), chlorobenzenes (CBs). We focus on impact material properties adsorption mechanisms organics. This highlights use sustainable eco-friendly pollutants, especially when combined with biological or chemical strategies. Biochar facilitates electron transfer efficiency between microorganisms, promoting growth dechlorinating bacteria mitigating toxicity organics through adsorption. Furthermore, can activate processes such oxidation nano zero-valent iron, generating free radicals decompose compounds. observe broader application bioprocesses treating soil, reducing impacts. Conversely, water-based integrating proved more effective, leading superior purification results. contributes theoretical practical pollutants.

Biochar can be used for multifunctional applications including the improvement of soil health and carbon storage, remediation contaminated water resources, mitigation greenhouse gas emissions odorous compounds, feed supplementation to improve animal health. A healthy preserves microbial biodiversity that is effective in supressing plant pathogens pests, recycling nutrients growth, promoting positive symbiotic associations with roots, improving structure supply nutrients, ultimately enhancing productivity growth. As a amendment, biochar assures biological through different processes. First, supports habitats microorganisms due its porous nature by formation stable micro-aggregates. also serves as nutrient source. alters physical chemical properties, creating optimum conditions diversity. immobilize pollutants reduce their bioavailability would otherwise inhibit However, depending on pyrolysis settings feedstock comprised contaminants polycyclic aromatic hydrocarbons potentially toxic elements activity, thereby impacting

Abstract Due to anthropogenic activities, heavy metal (HM) pollution in soils has increased, resulting severe ecological problems and posing a constant threat human health. Among various remediation methods, bacterial is relatively clean, efficient, minimally negative approach. However, agents face multiple environmental stresses, making them challenging achieve long-lasting stable restoration effects. To address this issue, supportive organic substances such as biochar can be added the soil with bacteria. According bibliometric studies, integrating bacteria extensively researched widely used for HM-contaminated remediation. By bacteria, metals remediated, conditions improved over time. Bacteria also better promote plant growth or contribute effectively phytoremediation processes when assisted by biochar. are still some distance away from large-scale use because of their high cost possible problems. Therefore, further discussion on interaction between integration approach, along efficiency friendliness, needed sustainable This paper discusses potential mechanisms biochar-bacteria-metal interactions, current advancements biochar-bacteria combinations treatment, application remediation, analyzes compares effect different ways feedstocks integrate Finally, future directions presented, evidence strategies improving commercialization implementation.

Biochar is an eco-friendly amendment for the remediation of soils contaminated with cadmium (Cd). However, little attention has been paid to influence and underlying mechanisms co-pyrolyzed biochar on bioavailability uptake Cd in paddy soils. The current study explored effects from peanut shells (P) maize straw (M) at different mixing ratios (1:0, 1:1, 1:2, 1:3, 0:1, 2:1 3:1, w/w), bacterial community fractionation soil, its by rice plant. addition, particularly P1M3 (P/M 1:3), significantly elevated soil pH cation exchange capacity, transferred mobile residual fraction, reduced availability rhizosphere soil. application decreased concentration tissues (root, stem, leaf, grain) 30.0%- 49.4%, compared control. Also, enhanced microbial diversity indices relative abundance iron-oxidizing bacteria Moreover, was more effective promoting formation iron plaque, increasing sequestration plaque than other treatments. Consequently, highest yield lowest accumulation were observed following application. This revealed feasibility applying facilitating Cd.
